Documentation in S3 method visr()

[ddsjoberg]

Some arguments are documented for each class/method. When these arguments are documented multiple times, the last one is used in the help file.

For example, the visr(x=) argument is documented as

• @param x Object of class 'survfit'
• @param x Object of class 'attritiontable' with each row corresponding to an inclusion step in the cohort and minimally a description and a count column

Only the last one is shown in the rendered help file.

Proposal to put all documentation at the top instead of per method.
@param x. We can use markdown syntax for a bulleted list to specify for which class x represents what.

@param x a visR object

• objects of class survift
• object of class something else
  @param x a visR object
• objects of class survift
